In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. silica ore was used as the test material.
jul 18, 2013 the makeup balls are mm forged alloy steel balls and the average ball consumption is 750 ore ground. In order to optimise ball size distribution inside the mill, based on the previous investigation, instead of using only mm makeup balls, a combination of and mm ball charge was used in one of the grinding lines.
balls, meaning that the ball size distribution had some effect on crushing and grinding however, the horizontal planetary ball mill is different than the tumbling ball mill in many aspects. djordjevic studied the influence of ball charge size distribution on the net-power draw of tumbling mill based on dem modeling.

commercial ball sizes 150 mm. number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. for the initial chargin of a mill, coghill and devaney defined the ball size as a function of the top size of the feed, i.e 0.40
the basic parameters used in ball mill design rod mill or any tumbling mill sizing are; material to be ground, characteristics, bond work index, bulk density, specific density, desired mill tonnage capacity dtph, operating solids or pulp density, feed size as and maximum chunk size, product size as and maximum and finally the type of circuit openclosed
dec 01, 2013 the total volume of the balls, Al powder, and water reached approximately 60% of the bottle height. five types of ball diameter were used: nominal diameters of and mm. By using the balls with each size, ball mill was carried out for
aug 21, 2020 In addition to high efficiency, it also has other advantages such as low noise, fine and uniform grinding grain size, and low environmental pollution. wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of dry ball mill.
